NONREFILLABLE BOTTLE.

Application-filed March 31, 1925. Serial No. 19,650.

This invention relatestol a non-refillable bottle, and has for an objectthe provisionv ings, of which- Figure l is a sectional view ofthe uppereng of the bottle with the parts attached; an

Figure 2 is a. plan view of the valve which forms one of the parts ofthe invention.

The form of the invention shown in the drawings is a preferred form,although it is understood that modifications in the construction andarrangement ofI the parts and in the character of the materials used maybe adopted without departing from the spirit of the invention as setforth in the appended claim.

The invention in its general aspects comprises a metallic cap which isattached over the top end of the bottle and, preferably,

crimped over its neck so as to be practically non-removable withoutbeing destroyed or broken. This cap is provided witha discharge orificein which an adjustable member is mounted for adjustment to hold thevalve within the cap in a tight position when the bottle yis not in use,especially when it is being shipped or stored. Within the cap, andpreferably seated on a suitable flexible flange, is a valve which whenit is released will move off its seat only when the liquid is comingfrom within the bottle to the outside, and which, when attempt is madeto pour liquid into the bottle from the outside, will be automaticallyseated to prevent the introduction of such liquid. In its furtheraspects the invention includes means on the valve for keeping it spaceda suitable distance at all times from the top Y of the cap so that theliquid will flow out when a discharge is desired.

In the preferred embodiment of the invention shown in the drawings, ,theidea 1s attachable to the neck l of the bottle which is provided with abody 2 at its uper end. A cap 3, preferably of metal, is disposed overthe neck of the bottle and is provided with an inwardly turned fiange lwhich will be crimped under the body 2. The capl is provided with adischarge orifice 5 threaded to receive a threaded body portion 6 havinga dependent stem 7 and a head 8.

The stem 7 is adapted, when the body portion is screwed into thedischarge orifice, to bear against the upper surface of a valve 9. Thisvalve comprises a plate portion l0, against the upper face of which thestem 7 bears, and a conical body portion dependent from said plateportion. The plate portion l0 extends beyond the conical body portionand acts as a flange to rest on a washer 11,

preferably of some flexible material, such as rubber, to form a tightseat for the valve. rI`he upper surface of the plate lO, at any desiredpoint, is provided with a projection or teat l2 which prevents thatportion of the plate from coming intimately in contact with the innerface of the cap, so that there is always a slight space between theupper surface of the plate l0 and the cap to permit of the discharge ofliquid through said space.

In the position of the parts shown in Fig. l, the valve is held tightlyagainst its seat by means of the stem 7, because the body portion 6 isscrewed firmly into the discharge orifice of the cap 3. By loosening orremoving this body portion 6, however, and inverting the bottle, thevalve 9 will fall off its seat by gravity and the liquid from the bottlewill flow out around the valve and out of the discharge opening 5,because of the fact that the valve is spaced slightly from the innersurface of the cap by reason of the projection l2. However, when thebottle assumes its normal position any attempt to pour liquid into thebottle will -cause said liquid to bear on the upper sur- ;face of thevalve and press it more firmly on neck, a cap to be disposed over saidneck,

the neck having a bead at its upper end, the

10 valve to prevent said surface from'lying too closely against the cap.when the bottle is inverted, a-plug adapted to be threaded into thethreaded opening in the cap and a stem on the lower end of the plugadapted to be placed against the valve as the plug is advanced to holdthe valve on its seat, the withdrawal of the plug permitting the valveto vmove'oli its seat.
